I've had my MacBook Pro without Touch Bar for coming up on 2 years. Never had any issues with this at all, I don't even have a case. It's in my backpack about 80% of travel time and storage. In my 18 years of experience in IT and repair, all of these images in the last 10 pages of posts actually show a point of impact. If it wasn't an impact hard enough, it would only crack the class, yet some of these images are cracking and distorting the display with black lines and such-- like that one user posted with images like Macbook Pro Screen Issue - Google Photos.
In servicing several tens of thousands of laptops, it isn't uncommon to find a person state that they have no idea what happened to the display, while something else ended up happening without their knowledge-- for instance, customer came in pretty hot headed about her display with a similar point of impact on her screen. She became very livid with me when I mentioned the there's an actual point-- a pin point area in which the display is cracking from, signifying a point of impact and accidental damage. She screamed at me and made a huge scene, while her son, about 12 years old or so, was sitting on the stool next to her. After about 10 minutes of talking back and forth and screaming at me and my leader, her son came out and said that he wanted to play with the computer and shut a Skittle on the screen. It broke, he put it back and didn't say anything until then.
I know this doesn't happen to everyone, especially if you don't have kids, but this isn't uncommon at all. I've never seen a thermal crack in a screen, I've never seen a crack appear on its own. There's going to be an act of force that had impacted the screen or surrounding areas to cause those cracks. Laptop screens that show a point of impact on the display don't occur spontaneously like the Big Bang theory. There's got to be more to the story, either known or unbeknown by these people. There-in lies the issue. These screens are quite durable, but strong enough to take a BB (which happened to be another customer that openly said he shot it with a BB gun because his friend said the screens were tough). Ha.
Either way, I hope that you all get your devices serviced one way or another, be happy with your Mac or switch to Windows, Apple would wish you the best either way. Do what works for you, and if that's switching to a Lenovo that will take a current counting time of 4 weeks to just diagnose a laptop I sent in for an obvious bend and out of warranty replacement, do it. For me, being a PC and a Mac user and supporter, Apple's service is pretty dang amazing with completed repairs often taking less than a week.
